It accepts DG.-4 and GRIP-4 insert styles, secured by a clamp-style holding method for rigid, repeatable positioning. The shank measures 1 inch by 1 inch with a shank length of 4.35 inches and an overall length of 6 inches. Maximum workpiece diameter is 1.97 inches. Groove width range runs from 0.157 inches to 0.187 inches. This toolholder is installed by machinists and CNC operators working in job shop or production environments.\u003c\/p\u003e\n\u003cp\u003eThe 2500452 is suited for external grooving applications across a broad range of workpiece materials, including steel, cast iron, stainless steel, non-ferrous alloys, and high-temperature alloys, corresponding to ISO material groups P, M, K, N, H, and S. The Heli-Grip series is a common choice on CNC turning centers where consistent groove geometry and secure insert retention are priorities. With a back-of-bar to cutting edge dimension of 0.94 inches and a head length of 1.65 inches, the holder provides adequate clearance for most standard external grooving setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal, right-hand orientation for standard CNC lathe setups\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for rigid, repeatable cutting edge positioning\u003c\/li\u003e\n  \u003cli\u003eCompatible with DG.-4 and GRIP-4 insert styles\u003c\/li\u003e\n  \u003cli\u003eGroove width range: 0.157 inches to 0.187 inches\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering ISO groups P, M, K, N, H, and S\u003c\/li\u003e\n  \u003cli\u003e1 inch by 1 inch shank cross-section with 4.35-inch shank length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with DG.-4 and GRIP-4 series grooving inserts.
